FIG. 6.

Unrooted neighbor-joining tree based on the aligned amino acid sequences encoded by the DNA polymerase gene from ΦJL001 and 28 other phages. M, Myoviridae; S, Siphoviridae; P, Podoviridae. A total of 659 residues of the aligned region, including gaps, were used for phylogenetic reconstruction. A Blosum 30 matrix was calculated with a gap penalty of 10.0. The numbers at the nodes are bootstrap values based on 1,000 resamplings. Bootstrap values less than 50 are not shown. Scale bar = 0.2 amino acid substitution per residue.
